Another object of the invention is to 'pro'-' vide a shoe of the character described which may 'be securedaroundthe inner tube of a casing and placed opposite a blowout or.

weak point .in the casing and which will be held in position by the tube and will not creep around the casing. A further objectoi the invention resides in the provision of a shoe of the character described which is formed of -nove1;m'eans "for fastening the same on the inner tube of the tire. 3 r i 7 Titan. the above and other objects in view the invention'has particular relation to certain novel features'of constructiombperation and arrangement of part-s, ahexamplej of which is'given in this specification and V illustrated in the accompanying drawings,
